Heat sink

Abstract

A heat sink includes a plurality of fins, each of which includes a first vent and a first baffle. Each baffle is extended at one side of the first vent, and each of the first vents of the fins is located corresponding to the first vent of an adjacent fin. The heat sink further has a base, on which the fins are installed in parallel.

1 . A heat sink, comprising: 
 a plurality of fins, each of which comprises a first vent and a first baffle extended at one side of the first vent, wherein each of the first vents of the fins is located corresponding to the first vent of an adjacent fin.    
   
   
       2 . The heat sink as claimed in  claim 1 , further comprising: 
 a base, on which the fins are installed in parallel.    
   
   
       3 . The heat sink as claimed in  claim 1 , wherein each of the fins further comprises a second vent and a second baffle extended at one side of the second vent.  
   
   
       4 . The heat sink as claimed in  claim 3 , wherein the first vent and the second vent are formed on the first fin and the second fin in an oblique manner, respectively.  
   
   
       5 . The heat sink as claimed in  claim 3 , wherein the first vent and the second vent of each fin are positioned substantially in a V shape relative to a vertical direction of the fins.  
   
   
       6 . The heat sink as claimed in  claim 3 , wherein each of the fins and the first baffle as well as the second baffle thereof are integrally formed as a single piece.  
   
   
       7 . The heat sink as claimed in  claim 6 , wherein each of the fins is processed by a punching process to form the first vent, the first baffle, the second vent and the second baffle.  
   
   
       8 . The heat sink as claimed in  claim 2 , wherein each of the fins further comprises an opening and the openings form an airflow passage when all fins are installed on the base.  
   
   
       9 . The heat sink as claimed in  claim 8 , wherein each of the fins is processed by a punching process to form the first vent and the first baffle when all fins are installed on the base.  
   
   
       10 . The heat sink as claimed in  claim 8 , wherein the fins are thin plates comprising copper, copper alloys, aluminum, aluminum alloys, or other metal materials.  
   
   
       11 . A heat sink, comprising: 
 a first fin, which comprises a first vent and a first baffle extended at one side of the first vent; and    a second fin, which comprises a second vent located corresponding to the first vent of the first fin, wherein the second fin is installed in parallel with the first fin, and the first baffle of the first fin is connected to the second fin.    
   
   
       12 . The heat sink as claimed in  claim 11 , wherein the second fin comprises a second baffle extended at one side of the second vent, which is back to the first baffle.  
   
   
       13 . The heat sink as claimed in  claim 12 , wherein the first fin and the first baffle thereof are integrally formed as a single piece by a punching process, and the second fin and the second baffle thereof are integrally formed as a single piece by a punching process.  
   
   
       14 . The heat sink as claimed in  claim 11 , further comprising: 
 a base, on which the first fin and the second fin are installed in parallel.    
   
   
       15 . The heat sink as claimed in  claim 11 , wherein the first vent and the second vent are formed on the first fin and the second fin in an oblique manner, respectively.  
   
   
       16 . A heat sink, comprising: 
 a first fin, which comprises a first vent;    a second fin, disposed at one side of the first fin and comprising a second vent located corresponding to the first vent of the first fin; and    a first baffle, disposed between the first fin and the second fin and located at the first vent.    
   
   
       17 . The heat sink as claimed in  claim 16 , further comprising: 
 a third fin, which is disposed at one side of the second fin and comprises a third vent; and    a second baffle, which is disposed between the second fin and the third fin and located at the second vent.    
   
   
       18 . The heat sink as claimed in  claim 16 , further comprising: 
 a base, on which the first fin and the second fin are installed in parallel.    
   
   
       19 . The heat sink of  claim 16 , wherein the first fin and the first baffle are formed individually and then assembled together.  
   
   
       20 . The heat sink of  claim 16 , wherein the first fin and the first baffle are integrally formed as a single piece.
